Application filed July 9, 192s.v serial N. 291,330.

Theinvention'is afurnace which ispro-V .vided with an inclosureat theV front to conipletely inclose the ends of the shaker* bars "and ash pan and which isk also 4provided with 5 a combination agitator and shaker bar.

` The object of theinvention is to provide a furnace in which the entire frontis com- 'n shown or-may be constructed to provide ak t furnace offany suitable type or design Itis pletely inclosed so thattdust or dirt yfrom lthe furnacexcannot escape.

y'1o Y Yvide a furnace havingl pivotally mounted grate barsvwith slidable agitating devices operable through the'journals of lthe grate' bars.

i I Another object-of the'invention'is to ypro- VVvide a furnace in which the grate bars may readily be removed from' the front'.

A further object of theinvention is to provide" a furnace with an auxiliary shaking e 20 apparatus in ,combination with means for dumping the clinker, both of which are 1nde-- pendently operated;` v

A still further object ofthe invention is to inclose the front lofl arfurnace to providea furnace with a'neat appearance.v t

' And a still further objectof theinvention is' to provide a furnace which is of a simple and economical construction.

With these ends infview 'the inventionemT` bodies a" furnace having aninclosure at the front and' removable grate bars which are arranged so that the grates maybe turned` Aover. or thev ashes shaken without Lturning the g'rates.-V v

Figure 5 .is a view showing a removableV j plate at the front of the furnace wliiclrmay v be removed when it is desired to remove the '150r g'ratebars. Y

Another `object of'the invention is to pro- Otherfeatures andadvantages ofl the in-V Figure 6 isa view showing a combination shaker handle.

In the drawings 'the' device is 'shown as it would bemade wherein numeral 1 indicates v the furnace casing, numeralQ the grategbars and numeral 3 the shaker handle. n

The furnace casing `l mayrv be made-fas understoodlthat this invention-'involves the lower portion ofthe furnace only including t'heshaker bars, ash pan and an inclosure at `the front, and `inay-be'used with furnaces for hot.air`, water,` steam or of any other type.v f

In the .design shown, the casing 1 is made l of a rectangular shape with an auxiliary cas-, ing-nor inclosure 4 at the front Which'mayr be made 'to completelyfinclose-the ends of the shaker bars and. ash panas shown. The

casing 4 isprovided vWith an upper plain Vdoor 5 whichis attached to the side-wall by 1a hinge k..6 and is held by a latchoperable n 'side operable by a nob 10. The nobs 7 and 10 are' pivotally mounted in the doors and on the 4inside of the doors are latches 1'1 which engage clips 12 on the side of the casing and it will be observed that byrotating the nobs from the outside of the door. itwill be'pos'sithe .clips to hold or openthe doors. The lower doorS is providedJwith an auxiliary 'door 13Y having a ventilator 14 initV which is operated by a -nob 15.` This door ispivlotally attached to the doorl Sas shown at ythe point 1 6. The. door 13 with the ventilator I 14 provides the only opening inthe front of thefurnace when: the doors and 8 are yclosed ble to case the latchesto engage or dis-engage so that the casing 4 forms a complete closure v for the furnace front. vIn the kdesign showny the remaining portion ofthe casing is formed with straight Walls, however it is understood designed in any other-manners. v

that this -is only typical as the casing maybe.

The-Vactualffurnace front as indicated by thenumeral 17 'isvmade' as shown -in Figure Y3 with an opening- 18 atthefbottom in which ice an ash pan 19 may be placed and above this opening is another opening 20 extending from the horizontal center of the grate barsl upward to the point 22 and in the lower edge, which is indicated by the numeral 21, are semi-circular openings 23 in which the outer 'ournals 24 of the grate bars are mounted. 's opening 20 is covered by ya plate 25 shown in Figure 5 which is provided with openings 26 to' fit over the'journals 24 and smaller openings 27 to lit over thumb Ascrews 28 to clamp the plate in place. It will be seen that as the plate is inserted in the position shown in Figure 3 the lower edge will be held by a flange 29 and when it is in place the thumb screws 28 may be tightened to clamp the flange 29 against the plate. The upper edge of the plate may be provided with a knob 30 by` which it may readily be removed and replaced; c The grate bars 2 are made as shownin Figures 3 and 4 with outer frames as indicated by the numeral 2, having longitudinal bars 31 and the frames are provided with the journals 24 at the front and also the journals 32 at the rear. The journals 32 are pivotally mounted in lcircular' openings 33 in a plate 34 at the back of the casing. The gra/ces are also provided with slidable members 35 the ed s of which are bent around the edges of the grate frames as lshown in Figure 2 .and indicated by the numeral 36. The members 35 are 'also provided with upy wardly extending flanges 37 which will agi- .tate any material upon the grate bars and therefore function as shakers when they are moved backward and forward by the yshaker handle 3 lshown in yFigure 6 which maybek hooked into eyes 38 at the yend of rods 39 which are attached to the slidwhle members35 through the flanges 37 as shown in Figure 3. The bars 39 will extend through the journals 24 which will make it possible to rotate the grate bars 2 and also operate the 5 slidahle members 35 independently. The

` journa1s24 yare provided with pins 40 at the sides which Vengage notches 41 in a hub 42 at the end of the shaker handle `3 as yshown in Figure 6 so that the hub 42 of this 'handle may be placed 4over the journals 24 and with the pins V4(5) in the notches 41 the grate bars readily be rotated to dump kclinkefrs lor the like. Theshaker handle 3 is provided with a handle 43 and at the end of the handle is a hook 44 that may readily be placed in the eyes 38 of the bars 39 as shown in Figure 3. Clips 45 may be provided 'at the sides of the furnace `casing upon which Ithe outer edges of the shaker hars 2 may rest.

It will be understood that changes ymay he made in the construction without departing from the spirit of the invention. Orne of which changes may be in the design of the casing, another may he in the use of the ifmclosure 4 on :a furnace with shaker bars of` and thru the trunnions at the forwar Vdraft regulated by the ventilator 14 or the auxiliary door 13 may be open. When it is desired to shake the furnace the hook 44 of the shaker 3 may be placed in one ofthe eyes 38 and by drawing it backward and forward one' of the slidable vmembers 35 will move and break up the fire and cause'the ashes to drop through the grate; and when itis des'red to dump the fire or remove the clinkers the hub 42 is placed upon the journal 24 and the grate raised as shown in dotted lines in Figure 2. Should one of the grates break or become out of order the plate 25 may readily be removed by loosening the screws 28 and the bar may then be raised and' drawn through .the opening 20 so that the grate bars may readily be removed and replaced from the furnace without tearing they furnace down. f

Having thus fully described the invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a-furnace grate vof the typewhere the grate members are pivotally mounted on trunnions eccentrically positioned in relation to the longitudinal axis of said members with the larger portions of themembers resting upon supports at the sides of the furnace thereby holding the grate members in a horizontal position, and where two ofy said grate members .are used in combination, plates with f kto said grate members, upwardly extending llanges at the front and rear edges lof said plates and inclined toward the central portion thereof to facilitate passing under the fuel bed on the grates and forming Scrapers, bars extending from the front of said s ends of the grates, sockets at the outer ends of the bars the dimensions of which are smaller than the trumaions allowing passage for shaker handle hubs thereover, and means on said forward trunnions to facilitate gripping by said shaker handle hubs.

2; In a furnace grate of f the pivotally mounted 4type having trumnionsl eccentrically positioned in relation to the longitudinal axis of said grate and with removable shaker nions, `scrapers sl-idably' mounted yon said grates and of sufficient length to maintain F$30 parallel relation between the Scrapers and grates and thereby prevent binding, upward 1y inclined langes at the front and rear edges of said Scrapers, bars extending from the 5 Scrapers thru the grate trunnions l at `the y front, connecting means at the ends of the bars smaller than thedianieter of the trunfr nions allowing passage of the shaker handle y hubs thereover, and means on the nrnnnionsy e for gripping and holding the hubs ofthe handles.
